6.1. Speed proportional control
Various inclinations can be set by frequency point setting.
The frequency command value on the slave side during inter-drive communication can be expressed
by the following formulas.
If inter-drive communication is not selected (=), point conversion is not performed.
Point conversion is performed only when the command “S” is received.
The frequency command value on the slave side during inter-drive communication can be expressed
by the following formulas.
If inter-drive communication is not selected (=), point conversion is not performed.
Point conversion is performed only when the command “S” is received.
